煤矿矸石不升井巷道充填技术研究

Filling Technology of Coal Mine Vermiculite Non-lifting Mine Roadway

本文就煤矿矸石不升井巷道充填技术进行研究,合理设计了矸石巷道充填技术的工艺流程,并研制了带式抛矸机作为作业面充填的关键设备,实现了大断面长距离的巷道连续充填,充填率达85%～90%,且矸石巷道充填的经济价值也非常可观,具有广泛的推广借鉴价值。

This paper studied the filling technology of coal mine vermiculite non-lifting roadway,reasonably designed the technical process of filling the meteorite roadway,and developed the belt throwing machine as the key equipment for the working surface filling,realizing the continuous filling of the roadway with large section and long distance.The filling rate reached 85%~90%,and the economic value of the filling of the meteorite roadway was also very considerable,with extensive value of promotion and reference.
